3510 External SCSI Enclosure

190-060 PS/2 External CD-ROM Drive Model 001
193-182 Enhanced External CD-ROM II Drive Model 005
191-053 PS/2 SCSI Storage Enclosure (3510-0V0)

SHS91F9233 IBM PS/2 SCSI External Storage Enclosure (BOO)

Warning! The 3510-020 is a clone-boxen enclosure! It's black and angular, unlike the rounded edges of the PS/2 machines.

3510 Enclosure

This little bad boy is the Cadillac of external single device SCSI enclosures. It has top and bottom ventilation grilles for the 35 watt PSU. I would bet that these would be sufficient for a CD-ROM.

The HD enclosure has a cylinder lock similar to those on the 95 series.

Open the 3510

Unscrew the single standard screw above the C-50 passthrough connectors. Pull the top cover forward about 3/4", lift it straight up.

3510 Layout


Looks like the cutout was added for later 3510s to make it easier to hook up cables. My 3510-001 lacks the cutout and it's a little difficult to plug the SCSI and power connectors in.

Open a Locked 3510

David Ress was faced with a locked box of goodies, but managed to open it:

1) Louis for good ideas
2) Hot coffee, decaf so your hands do not shake
3) Long nose needle plyers
4) Pocket screwdriver

1) Remove screw on back, slide cover forward, will go about 0.25 inches
2) Turn unit over.
3) Look between cover and bottom, and you will see the lock
4) Wedge pliers down onto nut, and turn.
5) Repeat 5 until nut freely turns with screwdriver blade
6) Once nut falls off, use screwdriver to remove lock nut.
7) With lock nut off, use screwdriver to remove locking bar.
8) Turn case over, slide cover off!

   If the lock is too tight to allow the top to slide forward enough to get at the nut:

Remove cover screw at back. Remove the four screws from the bottom.

Using a standard screwdriver, carefully pry the side away from the rear corners. There is a rib on the upper cover that slides into a matching slot on the plastic base.

Slowly! After both sides have been pried up and past the slot, this now allows you to turn 'er upside down, and let the metal frame hang down at back.

The rear pins are about 3/16th of an inch high. That's all you need. Now, notice the two slots in the plastic base at the front. Notice the metal tabs? Pry the plastic base to the rear. Remember, don't let the metal frame settle back down on the pins! Even better, there are two holes that the rear pins can fit into. Let 'er hang.

Now slide the PSU backwards. This should give you enough room to get in and take the nut off the lock and remove the catch.
